Verrucaria takagoensis is a species of saxicolous (rock-dwelling), crustose lichen in the family Verrucariaceae.

Found in semi-freshwater habitats in Chiba Prefecture, central Japan, it was formally described as a new species in 2001 by lichenologist Hiroshi Harada.

The lichen has almost spherical, exposed black perithecia measuring 0.1–0.2 mm in diameter, with brownish-black perithecial walls, and lacking a distinct involucrellum.

The periphyses are 5–10 μm long with pointed apices, while its ascospores measure 6–8 by 4–5 μm.

Verrucaria takagoensis has a translucent or almost transparent (semipellucid) brownish, thin thallus.
